I wrote a response to this, but then I realised I was responding to the claim that modern media was more derivative, rather than what you actually said, which was that modern media is more _meta_.
Can you go into that a little more? Do you have specific examples that make you sad?
The first example that comes to my mind is the show Community, which I really enjoy, and which doesn't make me sad at all.
P.S. an article I linked to in my original response was https://www.filfre.net/2025/01/the-crpg-renaissance-part-1-f... which I mentioned as it talks about a historical standout in the genre but puts it in the context of the copycats and the schlock. It's now irrelevant to my comment, but I'd like to link to it anyway.
